摘要/Abstract

摘要： 微电网中分布式发电可使微电网的电能质量增强，但线路阻抗不匹配时传统功率下垂控制方法不能保证负荷不对称功率的精确分配.针对此问题，提出了一种基于一致性和自适应虚拟阻抗的分布式负序功率均分控制方法.该方法通过引入负序虚拟阻抗使分布式发电单元按容量精确分配不对称负荷.设计了多智能体一致性算法，自适应调整负序虚拟阻抗，消除线路阻抗不匹配带来的影响，实现了不对称功率准确分配.仿真实验结果验证了该控制方案的正确性和有效性.

Abstract: Distributed generations (DGs) can be used for the power quality enhancement of microgrids. However， load imbalance power cannot be shared accurately among the DGs by using the conventional droop control method for considering the mismatched line impedance. To solve this problem， a novel distributed negative-sequence power sharing method was proposed based on both consensus and adaptive virtual impedance. The negative sequence virtual impedance of each DG was used by this method to achieve accurate negative-sequence power sharing. A multi-agent consistency algorithm was designed to adjust adaptively the negative-sequence virtual impedance， to eliminate the imbalance power sharing error among the DGs， and to implement accurately asymmetric power sharing. The simulation results verified the correctness and validity of the proposed method.

Key words: distributed generation (DG), microgrids, consensus control, negative-sequence virtual impedance, imbalanced power sharing
